Kai stood over the fallen T-Rex, his body already showing signs of wear from the relentless assault on the island's largest predator. The T-Rex's breathing was heavy, each exhale shaking the ground beneath it as it struggled to get back on its feet. Kai had landed several powerful blows, but he knew this wasn't over yet. The creature was too strong, too resilient. This was the apex predator of the island, and it wouldn't go down easily.

He was still catching his breath when the T-Rex roared once more, shaking off the debris and pain. Its fiery eyes locked onto Kai, and in that moment, Kai knew it had no intention of letting him walk away.

"Damn," he muttered, rolling his shoulders as he prepared for another round.

The T-Rex lunged at him, its massive body moving with surprising speed for its size. Kai's instincts flared—his Observation Haki guiding him as he quickly sidestepped the creature's powerful jaws. He could sense its next move before it happened, a brief flicker in the air warning him of the danger.

Without thinking, Kai ducked low, dodging the T-Rex's swinging tail that could have easily crushed him. His body moved in sync with his instincts, but it wasn't enough to simply avoid the attacks. He needed to strike back.

Kai leapt onto the dinosaur's back, gripping its thick, scaly skin as he climbed up toward its head. The creature roared in frustration, thrashing around as it tried to shake him off. Holding on tightly with one hand, Kai summoned Armament Haki to his other fist, his skin turning black as the hardened energy coated his knuckles.

"Let's see how you like this!"

With a grunt, Kai drove his fist into the T-Rex's back. The impact was powerful, a shockwave rippling through the creature's body. The T-Rex roared in pain, its massive form buckling slightly under the force of the blow. But it wasn't enough. The creature twisted violently, and Kai was thrown from its back, landing hard on the ground.

Before he could get back on his feet, the T-Rex lunged again, its jaws snapping shut just inches from his face. Kai rolled out of the way, his Observation Haki blaring in his mind, warning him of the imminent danger.

He scrambled to his feet, panting as he summoned Blue, pulling a large boulder toward him. With a powerful motion, he hurled the boulder at the T-Rex, striking its side. The creature stumbled but didn't fall. Its endurance was incredible.

"This thing just won't go down," Kai muttered, frustration creeping into his voice.

The T-Rex roared, charging again. Kai braced himself, using both Observation Haki and his sharpened instincts to anticipate the beast's movements. He dodged left, then right, weaving around its powerful strikes. His heart raced, but his mind was clear—focused.

As the T-Rex prepared to swipe at him again, Kai saw an opening. He channeled Armament Haki into both of his fists, then launched himself at the beast. With a powerful leap, he landed on its chest, driving both fists into its torso. The impact sent a shockwave through the creature's body, but the T-Rex still didn't go down.

The beast roared in fury, twisting its body to throw him off once more. Kai was tossed into the air, but he summoned Blue, pulling himself toward a nearby tree and avoiding a deadly fall. The T-Rex's roar shook the jungle, its eyes glowing with primal rage.

Kai wiped the sweat from his brow, his muscles aching from the intense fight. His Observation Haki had kept him alive this far, but he needed something more to end this battle. Something stronger.

That's when the thought crossed his mind.

Hollow Purple.

He had tried it before, but it had failed. Combining Blue and Red into one devastating attack was dangerous, and he hadn't mastered it. But this was his chance to end the fight once and for all.

The T-Rex charged again, and Kai made his decision. He planted his feet firmly into the ground, extending both hands as he summoned Blue in one hand and Red in the other. His heart raced as the two forces crackled with energy, swirling violently in his palms.

The T-Rex was almost upon him, its massive jaws open wide, ready to tear him apart.

"Now or never…"

Kai forced the two energies together, creating a swirling vortex of destruction between his palms. The combined power of attraction and repulsion clashed, forming a dark, pulsating sphere.

"Hollow… Purple!"

With a roar of his own, Kai unleashed the attack. The dark sphere of Hollow Purple shot forward, colliding with the T-Rex. For a split second, there was silence, then the sphere detonated, unleashing a massive shockwave that tore through the jungle.

The T-Rex was caught in the blast, its body disintegrating under the sheer force of the attack. Trees were uprooted, debris scattered, and the ground itself seemed to tremble as the energy ripped through everything in its path.

When the dust finally settled, the T-Rex was gone. Completely annihilated.

Kai stood there, panting heavily as he stared at the devastation his attack had caused. His body trembled from the exertion, his muscles screaming in protest. He had done it. He had finally mastered Hollow Purple—at least, to some degree.

But the cost had been high.

Kai collapsed to one knee, his vision swimming as exhaustion took hold. He had pushed his powers to their limit, and now his body was paying the price. His head pounded, his limbs felt like lead, and his chest heaved with labored breaths.

"That… was too much," he muttered, his voice barely audible.

Despite the overwhelming fatigue, a small smile tugged at his lips. He had won. The T-Rex—the island's most powerful creature—had been defeated.

Aftermath

Kai dragged himself back to his base, his body aching from the intense fight. Every step felt like a struggle, but the thought of rest kept him moving forward. He had survived. He had beaten the island's apex predator, and now there was only one thing left to do—prepare for his escape.

Back at his base, Kai lay down, staring up at the night sky. The fight had taken everything out of him, but he was still alive. His armament haki had shown itself more clearly during the fight, and while it wasn't fully under his control, it was progress.

His thoughts lingered on the Hollow Purple attack. It had been unstable, difficult to control, but it had worked. It was a glimpse of what he was truly capable of—if he could master it. But for now, he would focus on recovering and making the final preparations for his escape.

As he reached his base, Kai sat down on the stone floor, letting out a long breath. The battle had taken a toll on him, but he felt a sense of accomplishment, of closure. The island had been his home for nearly two years, but now it was time to move on.

He looked at the log pose sitting on the small shelf he had made, the needle still pointing steadily in one direction. His escape was within reach, and soon, he would be leaving this island behind.

But first, he needed to rest.

Kai closed his eyes, allowing his body to relax for the first time in what felt like days. He had two weeks left. Two weeks to prepare for whatever came next.

And when the time came, he would be ready.
